Optimizing Comfort and Energy Savings in a Montréal Apartment Building with a Bosch Multizone Heat Pump
As part of our many HVAC installations in Montréal, we were recently called in to upgrade the heating and cooling system of a 6-unit residential building located in the Rosemont–La Petite-Patrie borough. The building owner was looking for a solution that would provide individual comfort for each apartment, reduce energy consumption, and qualify for available grants. After a thorough evaluation, we recommended and installed a Bosch BOVA36HDN1-M20G multizone heat pump, connected to several Bosch Climate 5000 indoor wall units.
This project perfectly illustrates our expertise in multizone heat pump installations in Montréal and highlights the tangible benefits of a centralized, intelligent system in a multi-unit urban building.
Why Choose a Multizone Heat Pump for a Montréal Apartment Building?
Multi-family buildings present a unique energy challenge. In this specific case, each unit was previously served by an outdated, inefficient central oil heating system. The building owner wanted to lower utility costs while improving tenant comfort. The answer? A high-efficiency multizone heat pump, capable of cooling and heating each unit independently.
Key benefits include:
-
Independent zone control (each tenant controls their own temperature)
-
High seasonal efficiency SEER 20 / HSPF 10.5
-
Average heating bill reduction of 42% from the very first month
-
Eligibility for Hydro-Québec’s LogisVert grant program (up to $5,120 in subsidies)
Technical Details of the Bosch Multizone Heat Pump Installation
The system we installed consisted of:
-
A Bosch BOVA36HDN1-M20G outdoor unit (36,000 BTU, 230V, inverter technology)
-
Six Bosch Climate 5000 indoor wall-mounted units, all connected to the multizone system
-
An optimized network of conduits and cabling, fully concealed to preserve the building’s aesthetics
-
A wireless individual control system for each unit
The inverter compressor allows precise adjustments based on actual demand, reducing on/off cycling and extending system life. Each wall unit provides quiet airflow, an intuitive remote, and a washable filter for improved indoor air quality.
Challenges Faced During Installation and Solutions Provided by AirGreen
As with any complex urban HVAC project, several challenges had to be overcome:
-
Limited space behind the building for the outdoor unit: we designed a raised aluminum frame mounted on the load-bearing wall.
-
Restricted access to indoor units without disturbing tenants: installation was scheduled in staggered time slots with precise coordination to minimize disruptions.
-
Thermal insulation of exposed conduits: we used high-density foam with a PVC sleeve for year-round protection.
-
Low noise level required by the city: we installed an acoustic screen around the outdoor compressor to comply with local noise bylaws.
This level of technical execution demonstrates our expertise and ability to tailor every HVAC installation project in Montréal to the real-world constraints of the site.
Measurable Results: Comfort, Performance, Grants, and ROI
After three months of winter use:
-
Tenants reported stable, gentle, and quiet heat in their units.
-
The building owner saw a 42% drop in electricity bills, while completely eliminating oil heating.
-
Thanks to the Bosch multizone heat pump, the building now qualifies for multiple LogisVert and Rénoclimat subsidies, totaling $5,120.
-
Return on investment is estimated at 4.3 years, not including the increased rental value of the building.
